Bud Not Budy prediction

I predict that the book is about a teenage boy that moves somewhere. And he makes a jazz band. And when he moves he runs to the train and throws his bag up to his friend. And he is running by the train and gets on in the back when it is moving. Then when he gets there he likes it and he makes friends and goes to school. Then it is during a big war when the white do not like black. And they where killing and a lot of people going to jail.
